Just to get this thread on track:
I think it's actually pretty unfair to the Rangers org to single out their postseason chokes this decade for the 2010 WS, the 2011 WS, the 2015 ALDS, and the 2016 ALDS.
What a lot of people, including Sid Seixero, seem to forget is that the Rangers also lost a 13-game division lead in the second half of 2012, capping off that regular season with a rug sweep at the hands of the Oakland A's, who leapfrogged the Rangers for the West division crown.
Luckily the Rangers had one last kick at the can in the debut of MLB's Wild Card game. However, they ended up losing 5-1 against the 93-win, +6 run differential Baltimore Orioles, scoring their sole run in the first inning on a double play grounder off O's starter Joe Saunders.
